Standard charge at 0.2C5A under the condition of normal atmospheric pressure and the environmental temperature of 25°C±5°C and 45%~80% RH(unless otherwise specified, storage and charging should be conducted as this regime), then rest for 10min and discharge at 0.2C5A,0.5C5A,1C5A to 30V respectively. Charge/discharge cycle can be conducted for 3 times before meeting the Standards(the same below).

Measure initial status and initial capacity. Store for 28 days after standard charge, then measure final status and residual capacity at 0.2C5A to 30.0V; After charge/discharge(1C/0.5C) cycle can be conducted for 3 times , measure the recoverable capacity before meeting the Standards(the same below). |
